The experimental results showed that the amounts of α-aryl ethers were between 0.07 and 0.09 and those of β-aryl ethers were 0.56 (bamboo), 0.51 (beech) and 0.35 (Thuja)/C_6-C_3 of which uncondensed types amounted 0.25, 0.26 and 0.18, respectively. It was tentatively concluded that the polymeric system of the bamboo lignin is composed of about 10:68: 22 of ρ-coumaryl alcohol, coniferyl alcohol and sinapyl alcohol via similar linkages found in spruce lignin and ρ-coumaric acid (O.O7/C_6-C_3) is esterified at the terminal γ-carbons of the side chains of the polymeric system.
